Mocking interface that defines public clone method fails on Scala 2.13.6

[jrduncans]

ScalaMock Version

5.1.0

Scala Version

2.13.6

Runtime

JVM

Please describe the expected behavior of the issue

Creation of mock successfully compiles

Please provide a description of what actually happens

[error] ....weaker access privileges in overriding
[error] def clone(): Object (defined in trait MyInterface)
[error]   override should be public;
[error]   (note that def clone(): Object (defined in trait MyInterface) is abstract,
[error]   and is therefore overridden by concrete protected[package lang] def clone(): Object (defined in class Object))
[error]       mock[MyInterface]

Reproducible Test Case

public interface MyInterface {
  public Object clone() throws CloneNotSupportedException;
}

import org.scalamock.scalatest.MockFactory
import org.scalatest.funsuite.AnyFunSuite

class Test extends AnyFunSuite with MockFactory {
  test("should be able to mock") {
    mock[MyInterface] // fails to compile on 2.13.6
  }
}

As discussed in https://github.com/scala/bug/issues/12466 this behavior on Scala 2.13.6 is valid, so it seems ScalaMock needs to implement MyInterface by defining a public override of clone instead of leaving the protected abstract from Object.
